The rapid urbanization has exerted tremendous pressure on natural systems in mountains. As a measure of sustainable use resources, ecological footprint is an important basis for judging whether the development country or region within bio-capacity. Taking Dali Bai Autonomous Prefecture as example, this study comprehensively analyzes impact human activities mountain resources and environment from three aspects urbanization, land carrying capacity. results show that with rate 33% still...

Long‐wavelength track irregularities have obvious influence on ride comfort and running stability of high‐speed trains. Meanwhile, it brings risk to the inspection since ordinary equipment has difficulties in covering long wavelengths. Previous research effect long‐wavelength is rare. In order find relationship between vehicle dynamic responses, a numerical vehicle‐track coupling model based multibody dynamics finite element theories established by using self‐compiling program. One case...

It is the trend that business to (B2B) has been becoming mainstream of e-commerce. With more and concentration on this field, however, recent research not defined what B2B Web site user satisfaction how evaluate it clearly. Also, traditional scales, such as information (UIS), end-user computer (EUCS) customer (CIS), are just focus system (IS) environment, but fit e-commerce environment very well. This article establishes "a Scale E-commerce Website Customer Satisfaction" (B2B-ECWCS) with...

Driven by new business, data and technology, the Internet-of-Things(IoT) has gradually evolved from a local Internet-of-Things wide-area to prospective global Intelligent Internet-of-Things(IIoT). This article analyzes typical business evolution requirements such as AR/VR, smart factories intelligent transportation then extracts 6S characteristics of Internet-of-Things. As development unfolds in trend, traditional fixed-mode architecture idea centralized management cloud are no longer...

As an important means of transportation, high-speed rail plays a very role in promoting the development urban agglomerations China. The Great Pearl River Delta is speeding up construction to shorten space-time distance between cities and promote regional integration. This paper, sorting out main problems existing (HSR) analyzing three effects HSR on development, i.e., corridor effect, breakthrough effect economic boundary integration factors. study proposes strategy from aspects connection...

To solve the problem of backward warehouse management, low operation efficiency and incomplete information this paper introduces passive RFID technology, designs Passive Technology Warehouse Management System (PRWMS). The system includes four layers architecture, integrating resources perception, access, platform application, which can effectively improve management segmentation. This also studies characteristics technology in factory scene, explores application PRWMS key businesses such as...

The security management of information system refers to the establishment effective protection mechanism for hardware, software and data in ensure normal operation system, free from accidental or malicious reasons, such as: damage, change, disclosure other acts natural factors, that can operate continuously reliably, user-oriented service is not interrupted. In view current situation frequent network problems, unclear weak awareness, this paper proposes implements an based on big technology...

Taking science and engineering universities humanities in 31 provinces as the main research subject, this paper uses Malmquist index gray management model to measure evaluate changes of industry-university-research innovation efficiency colleges i

This thesis emphaticly analizes and studies undergraduates' information demand behavior through investigation. Based on the conclusion of this investigation, we try to understand awareness, needs, seeking patterns evaluation items purchase intention for business in China. At end study, also make a few recommendations government service providers including universities' libraries or centers providers.

The evaluation of service quality is very important for fast food industry. This paper construct the system industry based on customer's point view, and put forward questionnaire in restaurant (FFR). Through investigation analysis, a valuable target FFR was constructed. Due to strong correlation between indicator variables, simultaneously order ensure minimum data loss, it can be used multi-dimensional reduces dimensions principal component analysis. Using SPSS statistical software change...

The slab ballastless track is the primary type of high-speed railway. When in severely damaged, typical way to replace it requires cutting jointless rail above damaged slabs. This paper discusses a solution pushing lateral direction (i.e., without rail) slab. To study feasibility and reliability this solution, finite element model for simulating construction process established. necessary spacing support slides capability device are analyzed. influence parameters such as release length...
